Check all screws for proper adjustment, you have  ruled out possibility of scope cause

chronogragh, if possible, to check health of rifle.

how is breech seal any blow by, do tissue test. Perhaps seal a little proud. Reason I mention proud breech seal is I myself receiving a fwb with such a seal causing same effect you are describing. 

have you been inside to check main spring and piston seal, main reason for chronograph, checking for consistency / fps.

I’m sure in time enough people will respond with possible causes and you can check off cause and effect and find a solution. If nothing else you can bend the barrel to bring POI to POA, providing you have consistency.

Cheers
